I have a question about Gondwanaland in the Cretaceous. It looks like
the Tyrannosaurids were located primarily (exclusively?) on Laurasia...
so what were the primary predators on the Southern Continent? Were
there analogs to the big predators we know and love, or something
completely different? Or is the fossil record down there not given up
that mystery yet?
The Late Cretaceous top predators of Gondwana were the Abelisauridae.
Not as big as the tyrannosaurids, nor were they particularly cursorial,
but like their distant northern kin they had stumpy arms.
Would that be a result of common origins or "lifestyle"?
